I need help with question 2 only. You need to know the case of "ZipCar: Refining the business model". Thanks

Read the "ZipCar: Refining the Business Model" case located in your course packet from Harvard Business Publishing Using what you have learned in class and the case evidence, write a response to the following four questions: l. What is the business model of ZipCar and how has it changed between December 1999 and May 2000? 2. For ZipCar, what are the factors that Chase has control over and thus can have a direct influence on performance and what factors are outside of Chase's control? This question is asking you to identify what aspects of the business model can be actively managed by ZipCar and what aspects of the environment simply have to be accepted as they happen.
